Molly and the Mutants

Book #2 of Far Flung Falls

About The Book

Molly and her friends take on giant mutant creatures in this second book in the hilarious and poignant Far Flung Falls middle grade sci-fi series set in 1980s Ohio—perfect for fans of Stuart Gibbs and James Ponti!

The mystery of the giant brother-stealing robot may have been solved, but a new set of troubles for Molly and her friends has just begun. Strange things are happening once again in Far Flung Falls. Where have all the pets gone? And who—or what—is behind the disappearances?

Naturally, everyone is looking to Molly for answers. Only this time, she’s as clueless as anybody else. What’s more, between dad’s new girlfriend, fifth grade homework, and her friend Margo’s wild schemes, Molly’s already got more than enough to deal with. Still, she feels the pressure of everyone’s expectations, and that pressure only mounts when the list of vanished pets grows to include her beloved cat, Crank.

Determined to find her, Molly hops back on her revamped bike, Pink Lightning, and together with Arvin, Leonard, and a few new faces, Molly sets off in search of answers. But nothing can prepare them for what they find…or what to do when it finds them.

An action-packed romp with heart.

“Maybe Molly McQuirter hasn’t always been the best big sister to her brother Wally, but she comes through when it really matters! Erik Jon Slagerup’s debut MOLLY AND THE MACHINE introduces a host of eccentric characters, a “villain” with a heart-rending origin story, a madcap adventure that won’t quit—and a heroine who finds more gumption, courage, and allies than she ever knew she had. Readers will be cheering her on from start to finish!”
